利用油井土、废玻璃作为主要原料，同时以碳酸钙作为造孔剂，通过控制烧结过程，最终制备多孔陶瓷材料，并利用XRD、SEM等对样品进行结构表征。本研究的目的是为了研究油井土、废玻璃、碳酸钙的比例以及烧结温度对孔隙率、机械强度、体积密度、吸水率、微观结构和结晶程度的影响。结果表明样品A3呈现大孔均匀的微观结构，是通过添加35wt％油井土、40wt％废玻璃、20wt％碳酸钙、5wt％硅酸钠在较低的烧结温度下来获得，其孔隙率、抗压强度、抗弯强度、体积密度和吸水率的值分别为52．38％、4．43 MPa、12．59 MPa、1．07 g／cm3和29．56％。并观察到其机械强度、吸水率和微观结构（孔径及孔径分布）有良好的相关性。
The porous ceramics were prepared by controlling the sinter process using the oily soil and waste glass consisting of the silica as the main material , and the limestone as the pore forming substance . The samples were characterized by the XRD , SEM and so on .An objective of this research was to investigate the influences of the amounts of oily soil/waste glass and CaCO 3 as well as of the sintering temperature on the porosity , mechanical strength , bulk density , water absorption , microstructure and crystalline phase .The results show that A 3 homogeneous microstructures of large pores could be obtained at low sintering temperature by adding about 35wt% oily soil, 40wt% waste glass, 20wt% CaCO3, 5wt%sodium silicate, leading to foams presenting porosity , compressive strength, flexural strength, bulk density, and water absorption values of about 52.38%, 4.43 MPa, 12.59 MPa, 1.07 g/cm3 , and 29. 56%, respectively .Good correlations among mechanical strength , water absorption and microstructure ( pore size and distribution ) were observed .
